(EN) Provided is a method for removing iron components from heater drain water in a power-generating plant, whereby the iron concentration in supply water to be supplied to a boiler can be decreased to a reference value or lower. The heater drain water (117) is discharged to the outside of the system when the iron ion concentration in heater drain water (117) discharged from a heater drain tank (116) is higher than a predetermined value, and the heater drain water (117) is supplied to a filtration apparatus (15) when the iron ion concentration in the heater drain water (117) discharged from the heater drain tank (116) is equal to or lower than the predetermined value. Alternatively, the heater drain water (117) is discharged to the outside of the system when a predetermined period of time is not elapsed, and the heater drain water (117) is supplied to the filtration apparatus (15) when the predetermined period of time is elapsed.
